A: Hi Robert! We're currently not offering 223 Rem ammo by the case. You can see our available options here: bulkammo.com/rifle/bulk-.223-ammo

A: Hello Christopher, These 55gr. FMJ rounds in .223 by Federal have new brass. They make excellent target rounds and great brass for reloading.

A: .223 ammo is limited to lower pressures than 5.56 ammo, and as a result, it will have lower velocities. The differences are minor for most people, but 5.56 ammo does have a slightly flatter trajectory at long range when compared to .223 ammo of the same bullet weight/type/manufacturer.

Posted On: 10/21/2011 By: Rob

A: The Mini-14 you have most likely has a .223 Remington chamber, meaning that you should fire only .223 ammo in it, and not 5.56mm ammo. If you're not sure on the chamber, contact Ruger with the serial number of your rifle, and they will probably be able to tell you.

A: Many factors affect ammo price. Materials costs are different in various parts of the world, and some companies use different materials for both the jacket and the case to reduce the cost of their ammo. Labor costs also vary wildly from one country to the next, and environmental regulations can add a hefty amount to the cost of ammo made in some countries. Beyond those factors, the quality control methods used to ensure dimensional consistency of projectiles, which is important for accuracy and precision, or the annealing of the cartridge case, which makes the case less brittle, can also drive up costs. Asphalt sealants on the bullet and other sealants on the primer can prevent moisture from entering the case and ruining the ammo, and a crimp on the primer will reduce the chances that the primer will pop out of the case and prevent a semi-auto rifle from functioning. All of these things cost money, and those costs are passed on to the consumer, who has to decide which ammo is right for him or her.

A: The bore diameter of 5.56 and .223 Remington ammo is identical - .224". Because .223 Remington ammo is loaded to lower pressures than 5.56 ammo, it will cause less wear (although the difference is slight) than the hotter 5.56 ammo.

A: It would not be ideal to use this ammunition for hunting small game. Try Hornady 52gr BTHP or Hornady TAP 55gr FPD.

Posted On: 10/18/2011 By: Andrew

A: Neither 55 nor 62gr .223 is inherently more accurate. Ballistics/trajectory out to longer ranges - 62gr will exhibit less drop due to its higher ballistic coefficient.

A: The bullet used in this federal American Eagle 223 Remington ammo is made of copper and lead. It does not contain any steel or other ferrous metals and will not attract a magnet. The case is made of brass – it will not attract a magnet either.

A: An AR-15 with a 1 turn in 9" twist rate should reliably stabilize, and therefore shoot accurately, .223 ammunition with projectile/bullet weights up to 73 grains. Therefore, 55gr ammunition will work very well with your Smith and Wesson M&P15.

Posted On: 10/7/2011 By: Nick

A: There is no steel in the projectile of this American Eagle 223 Remington round, or in the case. The materials used are brass, copper, and lead.

Posted On: 10/5/2011 By: Jason

A: We would consider this ammo to be fairly clean burning.

Posted On: 9/30/2011 By: John

A: This is the best price we can offer on orders under $25,000.

A: Dimensionally, the differences are in the weapon's chamber. The ammunition is dimensionally identical, but loaded to different pressures, with 5.56 being loaded to significantly higher pressures. It is safe to fire .223 in a 5.56 chamber, but not recommended to fire 5.56 in a .223 chamber. If you are unsure of what your rifle is capable of shooting safely, we recommend contacting the manufacturer or having the chamber checked by a gunsmith.

Posted On: 9/29/2011 By: Shannon

A: Yes, American Eagle .223 ammo is available in a 50gr hollow point. However, we do not carry it in the bulk pack format like this 55gr FMJ ammo.

Posted On: 9/28/2011 By: Jim

A: Yes, you can safely fire this ammo through a rifle with a 5.56mm chamber.

Posted On: 9/28/2011 By: Todd

A: Although a lead ban in the near future is unlikely, were it to occur, it would cause the price of ammunition to skyrocket in an almost unimaginable fashion.

A: We do carry XM856 tracers. They won't have any significant effect on the barrel or rifling.

Posted On: 9/28/2011 By: Mike

A: Dimensionally, the cartridges themselves are identical. However, there are chamber differences - specifically, the "leade," or the area where the transition to rifling begins - and .223 is "shorter" in this area than 5.56. Because 5.56 is loaded to higher pressures, it is safe to fire 5.56 only in weapons with 5.56mm chambers. .223 can be safely fired in either a .223 chamber or a 5.56mm chamber. If you are unsure of what pressure ammunition your rifle can fire, we recommend contacting the manufacturer.

A: An AR-15 in 5.56 with a 1/7 twist barrel will properly stabilize ammunition from 40 grains to 80 or more. With traditional projectile construction, a 77 grain bullet is the longest that will fit in an AR-15 magazine. There is a wide selection of projectiles that the 1/7 will stabilize out to the maximum effective range allowed by the velocity and ballistic coefficient of each load.

Posted On: 9/27/2011 By: Greg

A: Properly stored, ammunition such as this Federal .223 Rem can last for decades.

Posted On: 9/27/2011 By: Scott

A: Yes, this Federal .223 ammunition is safe to shoot and will reliably cycle in AR-15s chambered in 5.56x45.

Posted On: 9/27/2011 By: Prag

A: M193 is loaded to 5.56 pressures, with a corresponding higher velocity. This Federal 55gr ammunition is loaded to .223 pressures and has a lower velocity, but is safe to use in rifles with a .223 chamber. It may be loaded with brass that has a LC (Lake City) headstamp, but this can vary from lot to lot, with others having an FC (Federal Cartridge) headstamp.

Posted On: 9/27/2011 By: Greg

A: Certainly, a large part of the price difference between steel and brass ammunition is the fact that brass has more residual value. However, Federal ammunition is also made in the United States, and labor costs are higher here than in Russia, where Wolf is generally manufactured. In terms of quality, this Federal ammunition is made at the same factory that produces ammunition for the United States military.

Posted On: 9/27/2011 By: Ben

A: These Federal .223 cartridges are loaded to exacting specifications and will function well in any quality AR-15.

Posted On: 9/20/2011 By: Trevor Walters

A: Federal's 223 brass is great for reloading!
